Dogs come in all shapes and sizes - the UK Kennel Club recognises 221 different pedigree dogs, from Affenpinscher to Yorkshire Terrier (there are sadly no dog breeds starting with the letter ‘z’!).
Then there are all manner of crossbreeds, from so-called ‘designer dogs’ to lovable mongrels.
Each has its own list of positive and negative attributes, and it’s important to take plenty of time to think about what breed will fit into your lifestyle the best - for instance a smaller dog if you live in a flat, or a hypoallergenic dog if the mere mention of dog hair makes you think about sneezing.
There is even scientific research to guide you, in particular psychologist Stanley Coren’s groundbreaking book The Intelligence of Dogs.
Meanwhile, some will want a dog that has a calming influence on their home and family – avoiding more hyper breeds like Border Collies and Springer Spaniels.
Here are 12 of the most chilled dogs.

11. Greyhound
It may surprise non-Greyhound owners, but these incredibly fast pups are surprisingly calm when not enjoying a few speedy laps of the park. Noted counch potatoes, they'll sprint briefly but then sleep for hours, adapting well to quiet indoor life with minimal fuss or energy. | Canva/Getty Images
12. Saint Bernard
The most gentle of canine giants, the Saint Bernard is as calm as it is huge. They are particularly great with children - known for being 'nanny' dogs. | Getty Images
